So I jailbroke my iPhone 5 with Pangu 1.0.1, installed Cydia 1.1.14 via the Pangu app, initialized Cydia, updated to Cydia 1.1.15 and Pangu untether 0.2, installed Cydia Substrate, added a passcode and rebooted. No problems. Passcode was on, Find My iPhone was off. After this, I restored a backup using iTunes that had Find My iPhone turned on. This backup restored just fine but when I rebooted my phone which now had a passcode and Find My iPhone turned on. This resulted in a bootloop which I could only fix through a DFU restore. In addition, being that I had Cydia Substrate installed, I tried booting into safe mode by holding the volume up button but this didn't solve it either. My conclusion is that Find My iPhone is what's causing the bootloop. After rereading the change log for Cydia 1.1.15, I noticed that it only mentions fixing the passcode but and doesn't even mention anything about fixing or not fixing the Find My iPhone bug. Has anyone else gotten a bootloop as a result of Find My iPhone being turned on? Thanks in advance.
